自学 iOS - 三十天三十个 Swift 项目 第二天

继续做仿造着别人的第二个

1.首先下载 一些字体 网上搜索 "造字工房"

2.把下载的相应字体文件放到工程之中，就Ok了

不多说 效果如下

可以下面这个方法 检索项目里面所有的字体

   for family in UIFont.familyNames {

            for font in UIFont.fontNames(forFamilyName: family) {

                print(font)

            }

        }

代码如下

import UIKit

class ViewController: UIViewController {

    lazy var contentLabel = UILabel()
    lazy var changeBtn = UIButton()
    var tag: Int = 

    override func viewDidLoad() {
        super.viewDidLoad()

       /* for family in UIFont.familyNames {

            for font in UIFont.fontNames(forFamilyName: family) {

                print(font)

            }

        }*/

        self.view.backgroundColor = UIColor.black
        contentLabel.frame = CGRect(x: , y:, width:UIScreen.main.bounds.size.width - , height: )
        contentLabel.numberOfLines =
        contentLabel.textColor = UIColor.white
        contentLabel.font = UIFont.systemFont(ofSize: )
        self.view.addSubview(contentLabel)
        let content: String = "30 Days Swift\n\n 目前授权个人免费非商业使用\n\n 所以捐款了1元下了3款字体用来做试验\n\n 分别是造字工房劲黑，致黑和童心；"
        contentLabel.text = content

        changeBtn.backgroundColor = UIColor.orange
        changeBtn.frame.size = CGSize(width: , height: )
        changeBtn.frame.origin = CGPoint(x: UIScreen.main.bounds.size.width/ - , y: UIScreen.main.bounds.size.height - )
        changeBtn.setTitle("改变字体", for: .normal)
        changeBtn.layer.masksToBounds = true
        changeBtn.layer.cornerRadius = 50.0
        changeBtn.addTarget(self, action: #selector(changeFont), for: .touchUpInside)
        self.view.addSubview(changeBtn)
     }

    //MARK: - 点击事件
    func changeFont() {
        var fontName:String
        switch tag {
        case :
            fontName = "MFQingShu_Noncommercial-Regular"
            tag =
        case :
            fontName = "MFYueYuan_Noncommercial-Regular"
            tag =
        case :
            fontName = "MFWenYan_Noncommercial-Regular"
            tag =
        default:
            fontName = "AppleSDGothicNeo-Regular"
            tag =
        }

        contentLabel.font = UIFont.init(name: fontName, size: )
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}
